Alectinib Pharmacokinetic in Patients With NSCLC
Mexico45 participantsStarted 2022-05-01
Plain-language summary
This interventional study aims to determine the pharmacokinetics of orally administered alectinib with dose escalation from 300 mg to 600 mg twice daily in Mexican patients with advanced ALK-positive NSCLC.
The main question it aims to answer is: what will be the peak plasma concentrations of alectinib following sequential dose escalation (300, 450, and 600 mg BID) over nine weeks of pharmacokinetic evaluation (phase I) in Mexican patients with advanced ALK-rearranged NSCLC?
In phase I (on days 0, 21, and 42), oral alectinib will be administered twice per day (BID) to patients with ALK-positive NSCLC; starting with 300 mg BID in 21-day cycles and dose escalation in 150 mg increments until 600 mg BID. Blood samples will be taken before and after administration of each dose (on days 1, 22, and 43). The primary endopoints in phase I will be dose-limiting toxicity (DLT) and PK parameters (Cmax. maximum plasma concentration; Tmax: time to reach maximum concentration: AUC 1-12: area under plasma ocncentrations-time curve steady-state concentration). At the end of the last blood collection (at day 43), the evaluation of each cycle will be at 600 mg, and the participant will be discharged to continue their treatment on an outpatient basis. Phase one will finish on day 63 of the study.
In phase II, the chosen BID dose based on the phase I portion will be administrated until disease progression, development of unacceptable side effects, or withdrawal of consent. The primary endpoint in phase 2 is the overall response rate (ORR) per RECIST V.1.1.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
